Abstract: Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

Abstract: Devices, systems and methods for transitioning a UE to a new application server in response to a mobility event comprising, at a source application server handler: receiving an application ID (AC-ID) associated with an application client for a user equipment (UE); receiving a mobility event notification including a UE ID of the UE and a target data network access identifier (DNAI) to indicate a target edge data network to which a transition of a data connection for the application client is to be performed; encoding an outgoing transition request for transmission to a source application server to indicate the transition of the data connection from the source application server; and encoding an incoming transition request for transmission to a target application server handler (ASH) of the target edge data network to indicate the transition of the data connection to the target edge data network.

Abstract: Router advertisements may be used to configure multi-homed Protocol Data Unit (PDU) sessions. A first router advertisement message from a first PDU session anchor and a second router advertisement message from a second PDU session anchor may be decoded. A user equipment (UE) may identify, based on the first and second router advertisement messages, a first preference value associated with destination routes of the first network and a second preference value associated with destination routes of the second data network. The UE may determine a destination data network for a signal by comparing a destination route of the signal to destination routes associated with whichever data network has a greater preference value. The UE may prepare the signal with a prefix based on the destination data network.
